What does a 311 weigh on a trailer? How 'bout a 357?
 

What are the "real world" towing weights on the 311 SR1 and 357 SR1?

Can tell you my 272 SR1 , full tank (129 gal) and aluminum tandem trailer and all the misc. B.S. is about 7500/8000.
So by the time you get to 357 , it's gotta be 10,000.
Hope you got a stout tow vehicle:rolleyes:

I scaled my 357 with one of my cranes it was 10800 lbs. light on fuel. trailer is 1800 lbs. When set up right on the trailer the tongue will have 350 - 400 lbs and ride great.

It's funny that this thread is posted right now. I just came on to ask the same thing about a 302.:)

I ballpark my 311 full of fuel and normal lake gear at 9200.
I figure the trailer is 1700.
That makes for 10,900 thereabouts...

I've towed it with a '96 Cummins Dodge 3500 5-speed that was "turned up". That rig pulled it like it wasn't there.

I've towed it with a box stock Duramax/Allison 2500 and it pulled it great but it did "know" it was there.

I've pulled it with a chipped Powerstroke/Auto that was a split between the stock Dmax and the tweaked Cummins.

In all, the Dmax I liked best mainly because of the auto downshift feature of the allison...

Mike,
The 336 I have weighs 8450 dry according to Formula. 160 gal of fuel will add 960. My trailer comes in at 2700 and that puts me at 12110 with a full tank. I'd figure a 311 to be about 1100# lighter (7400# dry, 150 gal tank) and a 357 to be 7-800# heavier (~9000#, 190 gal).

It looks like steel vs aluminum trailer makes quite a difference, but either way, you're looking at at least a 3/4 ton truck to safely pull either. I tow with a 2500 Avalanche (8.1L, 4.10 rear) rated for 12,000 which pulls great but you know it's there, especially on parts of 696.

We're kind of up in the air right now - if the house sells, there is definitely no new boat in our future. OTOH, if we can't sell for what we want, we might just say f*** it and stay here for a few more years, and possibly buy a boat in the mean time.

I have the old 1990 catalog in our shop the 311 SR weight is 7400 and the 357 SR is 8950, sure don't make like that any more, good ole rough water hulls

I dont know where Formula gets there weight numbers from, My 311 on the trailer scaled in at 11300lbs. I weighed the trailer alone at 2800lbs. I had about 30 gallons of fuel, 7 gallons of water and my gear, so I figure the boat weighs about 8100lbs empty, 8300lbs w/gear, and 9200lbs with a full tank. So back to this 7400lb Formula rating, my boat has aluminum heads and exhaust. Does Formula still under scale there boats? I'd like to know because a 353 would sure be a great upgrade, but I dont know if my 9000lb Hydrohoist would hold it. I reluctantly tow it with a 1994 F150 Lightning. I set up the truck w/air bags,12000# receiver, 14000# ball, and a weight distributing hitch. The trailer is a triple axle steel Loadmaster with 6 wheel, 12" drum electric brakes. It tows good to about 65mph, after that it could get a little scary.

Your hoist will be real close, new 353 approx 8575 dry and yes your right for some reason what they advertise and what the boat actually feels like behind my f-250 is something totally different.

mY 357 DRY IS ABOUT 10,000#
I figure with a full belly of gas and all the stuff the wife brings along, it's about 14,000# going down the road.
